Longley rice 代码
Web4.1.1 Longley-Rice Model The Longley-Rice model is application to point-to-point communication systems in the frequency range from 40 MHz to 100 GHz, over different kinds of terrain. The main transmission loss is predicted using the path geometry of the terrain profile and the refractive of the troposphere. WebThe Longley-Rice model: Is valid from 20 MHz to 20 GHz. Calculates path loss from free-space loss, terrain and obstacle diffraction, ground reflection, atmospheric refraction, and tropospheric scatter. Provides path loss estimates by combining physics with empirical data. Creation Create a LongleyRice object by using the propagationModel function.
